Camber is the tilt wheel towards the top inside / outside of the line of the vertical axis when the vehicle viewed from the front. Large slope angle measured in degrees. When the wheels tilt the top toward the outside is called positive camber. On the positive Camber, wheels pushed into so as to Prevent the wheels from being separated. When the positive camber angle is too big to wear Occurs lead wheel on the outside of the positive wheels. Camber cause the steering Becomes lighter
When the tilt wheel towards the top in a so-called negative camber. Negative camber makes the vehicle tends to straight and stable. When the negative camber angle is too big to lead Occurs wheel wear on the inside of the wheel. Negative camber causes severe negative effects. Camber steering wheel bearing the freedom to grow and be Able to Increase the torque spindle bent.
Caster is the steering axis tilt the top towards the front or rear of the line of the vertical axis when viewed from the side of the vehicle.
When the straight road caster wheel drive function remained stable in a straight position while the steering wheel is released and when the vehicle turns sustain tire on the road surface properly.
Trail is the distance between the point of intersection of the steering axis with the midline of the road and the center point of tangency with road tires.For more information you can visit http://www.accesscasters.com/
Caster is positive when the steering axis tilts the top toward the back.
Vehicles typically use positive caster for generating vehicle stability when running straight and behind the wheel after turning power. When the positive caster is too big, it will cause more long trail behind the steering wheel and power grew, but the wheel tends to be more severe.
Caster is negative when the steering axis tilts the top towards the front. The negative caster makes steering is light, but the stability of the vehicle when running straight into less and less steering can be controlled so rarely used in vehicles in general.
Wheel angle (the angle difference of inflection) is the distance between the right wheel and the left wheel on the same center point both wheels when turning.
Is the difference between the distance of the front and rear wheel spacing right and left when the vehicle is viewed from above.
When the front wheels are smaller toward the inside of the rear wheel (seen from above), this is called toe-in. otherwise, the opposite arrangement is called toe-out.
